[DSA805] DSA-805-1 apache2 Vulnerability Scan
Vulnerability Scan Summary
Detailed Explanation for this Vulnerability Test
Several problems have been discovered in Apache2, the next generation,
scalable, extendable web server. The Common Vulnerabilities and
Exposures project identifies the following problems:
Marc Stern discovered an off-by-one error in the mod_ssl
Certificate Revocation List (CRL) verification callback. When
Apache is configured to use a CRL this can be used to cause a
denial of service.
A vulnerability has been discovered in the Apache web server.
When it is acting as an HTTP proxy, it allows remote attackers to
poison the web cache, bypass web application firewall protection,
and conduct cross-site scripting attacks, which causes Apache to
incorrectly handle and forward the body of the request.
A problem has been discovered in mod_ssl, which provides strong
cryptography (HTTPS support) for Apache that allows remote
attackers to bypass access restrictions.
The byte-range filter in Apache 2.0 allows remote attackers to
cause a denial of service via an HTTP header with a large Range
The old stable distribution (woody) does not contain Apache2 packages.
For the stable distribution (sarge) these problems have been fixed in
For the unstable distribution (sid) these problems have been fixed in
We recommend that you upgrade your apache2 packages.
